Hello. pretty new to speedrunning as well as this site. I had a submission For We're back a dinosaurs story over a month ago that still has not been verified. I attemtpted to message both moderators and have heard no response. what should I do next?

Both moderators have social media links. Try messaging them there.

If they still don't respond you can get them replaced with more active mods

I attempted to reach both of them via twitter and was unable. what would be my next step?

Report them trough the support hub

You can report them through the support hub, which would have you replace them as moderator. You’ll need to meet all requirements to be a mod before doing so.

If you don’t want to be mod, you’ll just have to wait for someone to eventually get to your pending runs.
